Ploidal Inheritance in the Slime Mould Dictyostelium discoideum: Haploidization and Genetic Segregation of Diploid Strains

Abstract

Diploid and metastable strains of Dictyostelium discoideum were cultivated in liquid medium for extended periods of exponential growth. A progressive increase occurred in the proportion of cells yielding stable haploid clones. The haploidization of a doubly heterozygous diploid yielded the expected segregant classes.
